PLOW-DOUBLETREE.,

SPECIFICATION forming part of Letters Patent No. 545,272, dated August 27, 1895.

Application led April 30, 1895. Serial No. 547|682. (No model.)

To @ZZ whom it may concern.-

Be it known that I, THOMAS N. DALLrs, a citizen ot the United states, residing at Spartanburg, in the county of Spartanburg, State 5 of South Carolina, have invented certain new and useful Improvements in Plow-Doubletrees, of which the following is a specication, reference being had therein to the accompanying drawings.

The objects of my improvement are to produce a light and inexpensive, but strong and convenient doubletree for a plow, to which two horses can be harnessed without danger of its knocking against their heels or of dragr5 ging on the ground, permitting also the horses to be closer to the plow, which renders the draft lighter, and allowing them to turn a shorter corner or to plow closer to an obstruction. I attain these objects by the construczo tion illustrated in the accompanying drawings, in which- Figure l is a perspective view of a plow provided with a doubletree constructed and secured to said plow in accordance with my z5 invention. Fig. 2 is a top view of the same with the addition of the whiffletrees.

In said drawings, A represents aplow-beam, having a standard A2, of any suitable construction, and handles B, as usual. The doubletree consists of a rod D, having two looped bends CZ about one-third of its length to constitute eyes for connection with the Whittletrees E. The other two-thirds of the rodD constitute braces D2 for the ends of the doubletree proper, said braces converging from the leyes d toward the sides of the plow-beam. Said braces are provided at their rear ends with eyes d2 to receive a bolt f, that is made to pass through them and also through a hole 4o made horizontally through the beam at a short distance in front of the plow/standard, a nut f2 being placed on the bolt f to clamp the parts together. To prevent the doubletree from dropping below thelevel of the end of the plow-beam the central portion of said doubletree is received within the looped end of a plow -clevis G, or within one ot the notches g, made, as usual, on the inner face of said loop, the clevis Gbeing secured, as usual, to the plowdoeam by a bolt or pin g2, passing vertically through the rear ends of the clevis and through the beam A. To prevent any excessive lateral displacement of the doubletree relatively to the end of the plow-beamfor example, when the team is turning a corner-a rearwardly-extended bend d5 is formed on the doubletree centrally of its length, the sides d* of said bend constituting abutments to bear against the sides of the front loop of the clevis, and thus any undue endwise inotion of the doubletree is arrested by the clevis. The whittletrees E are connected to the eyes CZ at the ends of the doubletree proper by hooked links e, as usual.

Having now fully described my invention, I claiml. In combination with a plow-beam and its clevis, a doubletree consisting ot a rod D passed longitudinally through the loop of said clevis, and having looped bends thereon, and two braces converging from said looped bends to the sides of the plow-beam, the rear end of said braces being secured to the plow-beam substantially as described.

2. In combination with a plow beam and its clevis, a doubletree consisting of a rod D having a rearwardly extended bend d3 in the middle of its length and passed longitudinally through the loop of said clevis, eyes d upon said rod and two braces integral with the rod D and converging rearwardly, the rear 'end of said braces being secured to the plow beam substantially as described.

In testimony whereof I atlix my signature in presence of two witnesses.
